where \(p_E\)  is the Euclidean Jacobi momentum. At present, the value of \(\Lambda \)  still could not be accurately determined from first principles,
therefore it should better be determined by experimental data. The experimental total widths of some
states [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]} that can be considered as molecules
can be well explained with \(\Lambda \)  = 1.0 GeV. Therefore we take \(\Lambda \)  = 1.0 GeV in this work to study whether the \(P_{cs}(4459)\)  can be
interpreted as a molecule momposed of \(\bar{D}^{*}\Xi _c\) .
